The text/css Media Type
Alternative Format: Original Text Document
RFC 2318 text/css Media Type March 1998 (1) external - the style sheet is linked to a document through a URI and exists as a separate object on the Web. The media type text/css is used when fetching the object, for example in the Content-Type and Accept header fields of HTTP [2]. (2) internal - the style sheet is contained within the document. A typical scenario is an HTML [3] document that contains a style sheet within the STYLE element. Due to this close relationship, HTML and CSS share the same top-level name ("text"). 4. Registration Information To: ietf-types@iana.org Subject: Registration of MIME media type text/css MIME media type name: text MIME subtype name: css Required parameters: none Optional parameters: charset The syntax of CSS is expressed in US-ASCII, but a CSS file can contain strings which may use any Unicode character. Any charset that is a superset of US-ASCII may be used; US-ASCII, iso-8859-X and utf-8 are recommended. Encoding considerations: For use with transports that are not 8-bit clean, quoted- printable encoding is recommended since the majority of characters will be CSS syntax and thus US-ASCII Security considerations: Applying a style sheet to a document may hide information otherwise visible. For example, a very small font size may be specified, or the display of certain document elements may be turned off. CSS style sheets consist of declarative property/value pairs assigned to element selectors. They contain no executable code. As with HTML documents, CSS style sheets may contain links to other media (images, sounds, fonts, other style sheets) and those links are typically followed automatically by software, resulting Lie, et. al.
